Comet NEOWISE over Vikos Gorge Image Credit & Copyright: [3]Constantine Emmanouilidi Explanation: Did the Earth part to show us this comet? Of course not, even if this image makes it seem that way. Pictured far in the background is [4]Comet NEOWISE as it appeared about two weeks ago over northern [5]Greece. Above the comet are many stars including the bright stars of the [6]Big Dipper ([7]also the Sorcerer, in [8]Aztec mythology), an [9]asterism that many people around the world used to find [10]the naked-eye comet as it hovered in the northern sky over the past month. In the foreground is [11]Vikos Gorge, the [12]deepest gorge on Earth, relative to its width. The gorge was slowly created by [13]erosion from the Voidomatis River over the past few million years. Capturing this image took a lot of planning, [14]waiting, luck, braving high winds, and avoiding local wolves. [15]Comet C/2020 F3 (NEOWISE) continues to [16]fade and is now best visible through binoculars as it [17]coasts back to the outer [18]Solar System.
